White Pine Weevil pupae typically reside in larval chambers within the current year's wood, where they have completed their development. In July, as the pupation stage occurs, the weevils are in these chambers, having previously fed on the inner bark and creating an environment that provides shelter. This area allows for protection during the delicate pupal stage and is crucial for their metamorphosis into adults. Understanding this behavior is important for pest management, as recognizing their habitat can aid in effectively targeting control measures during their vulnerable life stages.
